The deceleration is transmitted to the rotating shaft 12 through several stages of planetary gear transmission mechanism in the gear case 11, and the roller 6 attached to the rotating shaft 12 is moved gently in the direction of the arrow in FIG. 1, that is, so that the front side rises. Rotating rear endless conveyor belt 3
rotates in the direction of the arrow in FIG.
Rotate together in the direction of the arrow in the figure.

Then, the operator uses his right hand to hold the handle 1 at the rear end of the upper wall of the machine casing 1 together with the end of the leaf bag 13 at the rear of the machine casing 1.
4, and use your left hand to hold the grip lever 15 on the front part of the 1 side of the machine casing 1.
Hold the machine and carry it, as shown in Figure 1.
When the machine casing 1 is tilted forward and downward and placed on the brown ridge,
Since the tea buds on the upper surface of the tea ridges enter into the machine casing 1 from the front opening of the machine casing 1, the tea buds are pressed and held at the lower ends of the endless conveyance belts 2 and 3. Therefore, the tea buds are pulled up by the endless conveyor belts 2 and 3, and the tea buds are picked from the easily broken part near the lignified part of the petiole by the pulling force, and the picked tea buds are transferred to the endless conveyor belts 2 and 3. Therefore, as they rotate, they rise together while being held in a pinched state during plucking.
At the upper end of the rear endless conveyor belt 3, the tea leaves are discharged diagonally backward and upwardly from between the endless conveyor belts 2 and 3, and the tea sprouts placed on the rear endless conveyor belt 3 are transferred rearward by the rear endless conveyor belt 3, and then It falls into the leaf collection bag 13 from the rear end opening of the housing 1 and is stored therein.

Thereafter, by sequentially repeating the above operations, only the tea buds on the upper surface of the tea ridge can be picked and stored in the leaf collection bag 13.

(Embodiment) FIGS. 1 to 4 show an embodiment of this invention, in which openings are provided in the front lower part and the rear of the machine casing 1, and the lower ends of the endless conveyor belts 2 and 3 are inserted into the front lower openings. to appear. The upper roll 6 of the rear endless conveyor belt 3 is formed to have a large diameter, and the rotating shaft 12 to which it is fixed is fitted into a gear housing 11 on one side and a bearing 16 on the other side, and a motor 10 is mounted on the outside of the gear housing 11. Although not shown, the driving shaft of the motor 10 and the rotating shaft 12 are connected to each other by a several-stage planetary gear transmission mechanism housed in a gear case 11. The switch 8 is attached to the hand portion of the handle 14.

17, 18, 19 are rolls 4, 5, respectively.
The shaft rods 20 and 21 that rotatably support the tea leaves 7 are backing plates stretched on the back side of their contact portions in order to facilitate the pinching and transfer of tea buds by the endless conveyor belts 2 and 3.

FIG. 5 shows another embodiment of this invention, in which the upper and lower rolls 6 and 7 of the rear endless conveyance belt 3 in the above embodiment are made to have the same diameter. Other symbols indicate the same parts as in FIGS. 1 to 4.

(Effect of idea) This invention has the following remarkable effects.

(1) When the front end of the machine casing is placed on the tea ridges, the tea buds on the top surface of the tea ridges are pressed and pinched flat by the soft elastic front and rear endless conveyor belts, and are picked.
The picked tea buds are held in the pinched state at the time of picking and are transferred upwards and released diagonally backward and upwards, which prevents damage to the tea buds and allows for smooth and accurate work, resulting in good quality tea. The product value does not decrease.

(2) Plucking tea buds works in the same way as picking up the tea buds by hand, and the tea buds are always picked from the easy-to-cut part of the petiole near the lignified part. Therefore, the tea buds are picked mechanically, in the same way as traditional hand picking, and the lignified parts of the petioles, much less old stem parts, are not mixed into the picked tea buds. This allows you to accurately pick only the tea buds.

(3) Since the front and rear endless conveyor belts rotate continuously,
Tea picking work can be continued by sequentially repeating the operation of applying the front end of the machine to the tea ridges, and the worker can easily operate the machine and pick tea without worrying, and it can be used for a long time. It reduces fatigue during work and significantly improves work efficiency.

(4) Since the front and rear opposing contact portions of the front and rear endless conveyor belts are tilted rearward and upward, and the front endless conveyor belt is provided so as to protrude upwardly than the rear endless conveyor belt, the machine casing can be tilted forward and downward. When picking tea buds that are applied to tea ridges, the front and rear opposing contact portions of the front and rear endless conveyor belts and the front endless conveyor belts are inclined rearward and upward. Therefore, the picked tea buds are discharged diagonally backward and upward from the upper end between the front and rear endless conveyor belts, and the tea buds attach to the front endless conveyor belt and get caught up in it, or it rises while remaining on the front endless conveyor belt and moves in front of it. All of the tea buds are placed on the rear endless conveyance belt, transported rearward, and stored without falling from the upper end of the endless conveyance belt forward to the outside of the machine casing, thereby preventing loss of tea buds.

(5) Two endless conveyor belts placed in parallel in front and back are used to both pick and store tea buds, so the structure is simplified and the system operates easily and smoothly with low horsepower.

(6) It has a simple structure, can be manufactured easily and inexpensively, has no risk of failure, and is highly durable.
